Digital currency transaction framework
3. Option contract is a kind of agreement, which can give traders the right to buy or sell assets at a predetermined price before a specific date or on a specific date. Option contracts are trading derivatives that can be based on a wide range of underlying assets, including stocks and cryptocurrencies. These contracts may also come from information such as financial indicators. Generally, option contracts are used to hedge the risk of existing positions and speculative transactions.
If you want to participate in the transaction of digital currency, you must understand the digital currency ecosystem
It can be said that digital currency exchange is the most important part of the whole instry. Digital currency exchange provides investors and traders with the capital channel to buy and sell digital currency. At the same time, the trading activities of the exchange determine the price of many digital assetsaccording to coinmarketcap, the capital flow of digital currency exchanges is huge, with the average daily trading volume of the top five exchanges exceeding US $3 billion
there are hundreds of digital currency exchanges around the world, some of which operate globally in mainstream markets, while some focus on niche markets
for example, AAX is committed to providing services for digital currency traders and institutional investors, integrating the digital currency world with the global economy, and providing unparalleled first-class technical capabilities using the matchmaking engine supported by lseg technology
many substitutes have successfully occupied a certain market share shortly after their launch. What digital currency exchanges have in common is that they together provide the development soil for these alternative currencies
digital currency is no longer limited to bitcoin. Other digital currency assets, such as eth, XRP, BCH, usdt, LTC, EOS, xtz, etc., have a place in the portfolio and diversification strategies of many digital currency dealers
At present, there are many similarities between digital currency trading and foreign exchange trading, because the basic principles, tools, indicators and strategies used in foreign exchange are also applicable to digital currency trading. AAX College's digital currency trading section discusses these topics in depth and extensivelyblockchain protocol
blockchain is the underlying technology that makes digital currency possible. There are many kinds of blockchain protocols, and the technical characteristics, advantages and disadvantages of each protocol are slightly different
for example, bitcoin blockchain relies on mining and pow (proof of work) mechanism to process transactions, while another blockchain may use dpos (proof of entrustment) mechanism instead of mining. In addition to bitcoin blockchain, other noteworthy protocols include eth, hyperledger, EOS, XLM, Iost, kin, TRX and stem. Among these blockchain agreements, ETH (ethereum) is commendable in promoting the rapid innovation of the entire digital currency ecosystem
Ethereum platform was created by vitalik buterin, which indicates that developers can make better use of the resources of the platform by using their own programming language solidity. Ethereum has made blockchain technology all the rage, creating a new world of innovative decentralized applications on the basis of smart contracts and custom tokens. At present, most of the substitutes are based on Ethereum's erc20 standard
the district centered financial movement, or defi for short, is also basically based on the Ethereum blockchain agreement
financial services
for every service in traditional finance, Ethereum based defi applications have corresponding alternative versions for everyone to access. The defi app allows users to create stable currencies, lend money and earn interest, send and receive payments, get loans, trade, take positions in the forecast market, enter the real estate sector, and so on. Smart contracts are the key to making decentralized services possible. Once certain conditions are met, the smart contract will automatically perform the pre agreed activities
at the same time, traditional finance also began to provide new customized services for the field of digital currency. At present, some fund managers provide investors with the option of adding digital currency into their portfolios, the trustee provides security services for investors who invest a lot of money in digital currency, and many analysts in mainstream media (such as Bloomberg) also have a strong interest in digital currency
digital currency hardware
for those who like to build their own security measures, the huge digital currency hardware market can provide professional traders and long-term holders with the tools they need. Trezor and ledger are the most famous hardware wallets. They essentially provide the same value for digital currency traders, that is, a more secure way to store digital currency
of course, digital currencies stored in hardware wallets cannot be traded in the market. Therefore, digital currency traders usually allocate funds between the hardware wallet and the exchange according to a certain ratio according to their own trading style preference
There are so many activities ofdata aggregators and blockchain analysis
cross blockchain, which proces a large amount of data, and also spawns the emergence of sub instries, namely data aggregators and blockchain analysis instries. Companies such as coinmarketcap are the preferred source for quick inspection of digital currency and exchange data. They collect statistics on trading volume, liquidity, market value, price trend, circulation and the whole instry, such as the total amount of money, the number of markets, the market value of the instry and the proportion of BTC market value
people who are more interested in blockchain analysis can find the required data in websites like blocktivity. Here, you can view the relevant data of each indivial blockchain agreement, including the number of operations in the last 24 hours, the average number of operations in the last 7 days, the market value and Cui index, that is, the remaining available capacity after the actual usage of the current blockchain agreement. All in all, these websites can provide valuable insights for the blockchain instry
for example, the average number of operations of Ethereum in the past seven days was 667000, with Cui slightly higher than 50%, while the average number of operations of EOS in the same time range was 63 million, with Cui slightly lower than 50%. Technically, the performance of EOS protocol is more powerful than that of Ethereum. However, this can not prevent Ethereum from occupying 70% of the total market value of the most mainstream currencies
digital currency media and conferences
in today's world, almost everyone is the publisher of content. Without we media instry, such a large-scale instry will no longer exist. Digital currency has given birth to a wide range of media patterns, covering news media, KOL and related conferences for currency, public chain and code
digital currency head media include coindesk, cointegration, bitcoin magazine, decrypt, CCN, bitcoinist, newsbtc, etc. Some KOLs are also well-known, sometimes even more popular than the news media
YouTube celebrities, such as datadash, dollar villante, altcoin buzz, Ivan on tech and boxmining, have subscribers from 200K to 300K. In the field of digital currency trading, the top stars of cryptotwitter include venture coinist, cryptocred and cryptodon alt, with 211k, 140k and 120K fans respectively
if you want to have face-to-face communication with companies and people, digital currency and blockchain meetings should not be missed. Every year, there are many conferences around the world for investors, blockchain experts, start-ups, institutional financing, currency or agreement related communities. In 2019 alone, we sponsored and participated in blockchain live in London, the capital summit hosted by coinmarketcap in Singapore and the world mobile conference in Shanghai. We have had exciting meetings with other digital currency companies and major financial institutions, and established contacts with regulators from different jurisdictions
digital currency supervision
with the continuous growth of the market and audience of digital currency instry, in most cases, financial regulators are still developing relevant frameworks to protect investors and consumers. Regulators may take a very different approach, which is a challenge for companies operating across multiple jurisdictions
ring the ICO boom in 2017 and 2018, many projects were launched before the regulatory framework was established, while some projects did not meet the criteria of the jurisdiction and were suspended ring the fund-raising process. All this comes from how to classify digital assets, and the understanding of classification is constantly changing. At present, we divide digital assets into security token and practical token
in the past year, with the proposal of Libra, the promotion of supervision is also increasing. The central bank is also actively exploring the significance of blockchain technology to its policies and economic activities, and constantly publishing reports
the rapid development of digital money ecosystem
these components of digital money ecosystem are growing and developing in an orderly way, contributing to the increasingly sound instry. From the minority interest in 2009 to the active digital asset economy, digital currency has come a long way
However, in order to achieve the development and wide participation of the instry, a strong ecosystem is not enough. We need a better link between digital money and global finance. The better the combination of digital currency and traditional finance, the easier it will be for newcomers to understand the digital currency ecosystemfor every novice, as exchanges, financial services, media and regulators graally adapt to the expectations of mainstream consumers, the digital currency instry will further develop, which may improve investment outcomes
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.
Why develop digital currency? From the perspective of the central bank, there are six advantages:
first, to improve the convenience and transparency of economic transactions; second, to rece the high cost of the issuance and circulation of traditional paper money; third, to better support economic and social development; fourth, to help the comprehensive realization of Inclusive Finance; fifth, to rece money laundering, to promote the development of the economy and society Sixth, improve the central bank's control over money supply and circulation
steps of digital currency development:
the first step,
first, we need to download the source code of a blockchain system from git, such as choosing the backbone code of bitcoin to download the relevant source code
At the same time, prepare the corresponding compiling environment (c + + is recommended in Linux) and install the corresponding development environment and toolsthe second step and
code all need to be compiled, so you need to prepare the compilation environment and tools, download the environment compilation tools, configure
system environment variables, QT environment and other files, and compile commands are described in detail in the files in ITC source code
however, the construction of the system and development environment, program compilation and other processes are cumbersome, so it is not recommended for ordinary users to make their own. For developers, it may take 2-3 days to install and configure for the first time
the third step,
take bitcoin development as an example, it is the development environment of Q. after downloading the source code and configuring the environment, open the source code of the bitcoin core in qtcreator, configure relevant files and compilers, and start to try to compile the client of the bitcoin core
Step 4,
transform into your own digital currency, open each source file, find the corresponding local adjustment parameters, such as adjusting
the number of coins in each block, the total output, the adjustment difficulty, and so on. Then the most critical point is to change the name to your own currency
name as you want, and don't forget to replace the related icons in the resource folder. If all goes well, after re compiling, your new coin will be invented successfully
for the development of this digital currency, the technology is relatively professional, so it is better to have a professional team to assist
framework for digital currency development:
1. Build Ethereum private chain test environment and public chain node environment configuration
2. Ethereum transaction and confirmation principle
3. Ethereum JSON RPC interface
4. Ethereum transfer and withdrawal principle
5. The server connects Ethereum public chain interface, and its own server stores business data, Public chain storage transaction anonymous data
6, private key security processing
the following is the development code example:
for example, the common digital currency wallets in the market are:
app class: kcash Imtokenweb: myethereumwallet Google browser plug-in: metamask
one of the most commonly used is imtoken
blockchain transaction technology concept:
let's take a look at how blockchain transaction is handled with bitcoin as an example. In order to send a certain amount of bitcoin to another wallet, you need the following information: the address to send the funds to your wallet, the amount of cryptocurrency you want to send
the ID of the recipient's wallet
each transaction is signed with a unique confidential private key. Once the payment is signed by the sender, it becomes publicly available. The transaction still needs to be confirmed so that the payee can get the money. In order to confirm the transaction, it is necessary to generate a new chain block
these blocks are generated by complex mathematical calculation to find the unique key. It takes 10 minutes to create a new block, and the person who finds the key gets a certain amount of coins as a reward. Once a new block of the chain is created, it is not possible to remove it from the database or change the information in some way. Therefore, blockchain transaction is final and irreversible
three core advantages of digital currency:
first, digital currency is a fair currency
digital currency has no specific issuing institution, is not issued by a country, only depends on a specific algorithm, which means that digital currency can not be manipulated by manipulating the number of issues, so digital currency is a free, non-state currency
we can see that there are many countries that directly recognize the virtual currency, so if there is a demand, it needs a trading platform
many investors who want to build a virtual currency trading platform now, why can't they go to these areas to build a trading platform? Building a virtual currency trading platform is a good business opportunity, isn't it
Second, the security factor of digital currency is higher.
although the emergence of paper money facilitates the transactions in our daily life, there are risks of being stolen and received. Although e-money can avoid these risks, there will be new problems such as theft and swiping
digital currency can avoid the above problems. And broadcast every transaction record on the network. Yes, all nodes save all the currency circulation information, so that any node can easily find the currency circulation before the transaction
Thirdly, the transaction of digital currency can realize anonymous transaction. Although you can query the flow information of each account according to the local complete transaction recordsbut we can't know who the owner of this account is, and no one has the ability to manipulate the digital currency on other people's accounts, which protects the privacy of users
